Click Capture SELEX for the Identification of Click‐Modified Aptamers Targeting Small Molecules in Solution

Chemistry – A European Journal, EarlyView.
Using kanamycin A as a model target, we developed click‐capture SELEX to identify nucleobase‐modified aptamers capable of binding small molecules in solution. This approach enables flexible incorporation of nucleobase modifications via CuAAC, allowing the chemical properties of the aptamer to be tailored to the target molecule.

Slow Release of Bioactive Alcohols From Butenolide Polymers and Coatings

Chemistry – A European Journal, EarlyView.
In this study we have reported the acid‐mediated release of bioactive alcohols from biobased alkoxy butenolide derived copolymers and coatings. It can potentially be applied for slow release of odors, pesticides, or drug‐related compounds from biobased polybutenolides.

A DFT Study on the Mechanism of Selective Formation of Substituted Azepines From 1‐Azabutadienes and Cyclopropanes

Chemistry – A European Journal, EarlyView.
The origin of the unusual regioselectivity in the Mg‐catalyzed cyclization of azadiene‐type imines with cyclopropanes is elucidated by DFT calculations. Although five‐membered rings are typically favored, energy decomposition analysis reveals that severe steric congestion induces a highly distorted transition state, rendering the five‐membered pathway ...

Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers

Chemistry – A European Journal, EarlyView.
Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.
